In order to conveniently salvage the deposit in the dust fall water tank 6, and prevent that the water in the dust fall water tank 6 from overflowing from its top end opening part, the top of dust fall water tank 6 is opened and chiseled has two rectangular shape salvage mouths 62 and two circular mouths 63 of wearing, and two circular mouths 63 of wearing set up in the position between two rectangular shape salvage mouths 62, weld on the lateral wall of dust fall water tank 6 have rather than the inside overflow square pipe 61 that communicates.

In this embodiment, can salvage the dust deposit of piling up the bottom in dust fall water tank 6 through salvage mouth 62, under equipment operation state, the dust that gets into in dust fall water tank 6 increases gradually, after the dust formed the deposit, can lead to the water level in the dust fall water tank 6 constantly to rise, can discharge in dust fall water tank 6 through overflow side pipe 61 with the water after rising, avoids water to spill from salvage mouth 62 department.

In order to let the dust in dust collection box 4 discharge into dust fall water tank 6 more efficiently, and prevent that the dust from diffusing to the atmosphere, fan 41 is installed to the top embedding of dust collection box 4, the lower surface welding of dust collection box 4 has two dust exhaust pipes 42 rather than inside intercommunication, the circular mouth 63 that wears that corresponds the setting is all passed to the one end that dust collection box 4 was kept away from to every dust exhaust pipe 42, the bottom of every dust exhaust pipe 42 is submerged by its inside water after inserting dust fall water tank 6 promptly, the inner wall of every circular mouth 63 that wears all with the outer wall in close contact with of the dust exhaust pipe 42 that corresponds the setting.

In this embodiment, can blow down through fan 41, let the dust in the dust collection box 4 carry to the dust exhaust pipe 42 more fast then, the efficiency in dust fall water tank 6 has effectively been accelerated to the dust, because the outer wall of dust exhaust pipe 42 closely laminates with circular mouth 63 inner wall of wearing, so can prevent that the dust from outwards discharging from the gap between circular mouth 63 of wearing and the dust exhaust pipe 42, and the bottom of dust exhaust pipe 42 is submerged by the water logging, so can prevent that the dust from arranging outward from the port department of dust exhaust pipe 42, effectively prevent the dust from diffusing to the atmosphere, the effect of dust fall processing has further been improved.

In order to improve the mixing efficiency of mixture in agitator tank 1, and reduce the cost of maintenance of equipment, a plurality of stirring boards 71 are installed to the screw thread on the outer wall of stirring roller 7, every stirring board 71 is close to the equal fixed welding of one end of stirring roller 7 and has screw post 712, every screw post 712 all with stirring roller 7 threaded connection, the axis body one end of stirring roller 7 extends to agitator tank 1's outside and with externally mounted's motor output end fixed connection, it has a plurality of rectangular shape openings 710 to cut on the stirring board 71, a plurality of toper nails 711 have all been welded at the both ends that stirring board 71 kept away from mutually.

In this embodiment, will stir board 71 threaded fixation on stirring roller 7 through screw post 712, the convenience is carried out the dismouting to stirring board 71, receive the wearing and tearing back when stirring board 71 uses for a long time, only need take off it and go on more can, need not to replace whole stirring roller 7, cost of maintenance has been saved, because the welding has a plurality of toper nails 711 on the stirring board 71, can form stronger grabbing power to the mixture, ensure that the mixture can roll in agitator tank 1, be favorable to the mixture between the different materials, the mixing efficiency of mixture has effectively been improved.

In order to improve the convenience of receiving the finished product material, seal assembly 10 comprises layer board 101 and if cardboard 102, layer board 101 movable mounting is on limiting plate 9, layer board 101 both ends of keeping away from mutually all with the inner wall sliding connection who corresponds the supporting seat 8 that sets up, the lower fixed surface of layer board 101 installs the cylinder pole 103 of a plurality of perpendicular settings, the bottom of every cylinder pole 103 all passes the round hole of digging on the limiting plate 9 and rather than swing joint, the top welding of layer board 101 has a plurality of cardboards 102, every cardboard 102 all imbeds in the discharge opening of 1 bottom of agitator tank and is connected rather than the block.

In this embodiment, through cylindric lock 103 with layer board 101 movable mounting on limiting plate 9, ensure that layer board 101 can go up and down to move, after layer board 101 rebound, in 1 bottom opening of cardboard 102 embedding agitator tank, can carry out the shutoff to the feed opening of agitator tank 1 then, if layer board 101 rebound, after cardboard 102 extracts from 1 bottom opening of agitator tank, can discharge finished product mixture from agitator tank 1 in, the convenience of finished product material collection has effectively been improved.

Example 3

Referring to fig. 1-5, a further improvement is made on the basis of embodiment 2:

in order to improve the fastness of layer board 101 and agitator tank 1 connection, conveniently carry out lift adjustment to layer board 101, the both ends that layer board 101 kept away from mutually all are equipped with two sliders 105, every slider 105 all with the inner wall sliding connection who corresponds the supporting seat 8 that sets up, lie in all wear to be equipped with horizontal inserted bar 104 jointly on two epaxial cylinder poles 103 of same Y, every horizontal inserted bar 104 all is located the top of limiting plate 9.

In this embodiment, after the top of layer board 101 and the butt joint of the bottom block of agitator tank 1, penetrate horizontal inserted bar 104 and be located two epaxial cylinder poles 103 of same Y, it is spacing to horizontal inserted bar 104 through limiting plate 9, prevent horizontal inserted bar 104 downstream, can fix a position cylinder pole 103, ensure that cylinder pole 103 can carry out the outrigger to layer board 101, the fastness of layer board 101 with the 1 block of agitator tank being connected has been guaranteed, take out horizontal inserted bar 104 from cylinder pole 103, cylinder pole 103 loses spacingly this moment, can slide downwards along the round hole that cuts on the limiting plate 9, conveniently remove layer board 101 downstream, the convenience of layer board 101 lift adjustment has effectively been improved.

In order to prevent the waste of materials such as asphalt, mineral powder and aggregate in the putting process and save the production cost, the butt joint port 32 is arranged on the upper end face of each aggregate blanking cover 3, and the feed hopper 20 is welded at the opening at the top end of each blanking tower 2 and the butt joint port 32.

In this embodiment, can let the material concentrate together through feeder hopper 20, then can be stable landing to unloading tower 2 and aggregate unloading cover 3 inside, avoid the material to scatter to unloading tower 2 and the outside region of aggregate unloading cover 3, reduce the waste that causes the material, effectively reduced manufacturing cost.
